An exemplary embodiment of data processing environment 100 includesclient devices 102, 106 and 108 connected through network 104 andconnected through wireless communications 120. In one embodiment, dataprocessing environment 100 depicts client devices 102, 106 and 108operating in the same environment, connected and communicating throughnetwork 104 and wireless communications 120. In various embodiments ofthe present invention, client devices 102, 106 and 108 may beworkstations, laptops, personal computers, personal digital assistants,mobile phones, or any other devices capable of executing programinstructions. In general, client devices 102, 106 and 108 arerepresentative of any electronic device or combination of electronicdevices capable of executing machine-readable program instructions, asdescribed in greater detail with regard to FIG. 4. In alternateembodiments, data processing environment 100 can include other instancesof client devices 102, 106 and 108 (i.e. can have more or less).

Client devices 102, 106 and 108 include system software 110, and userinterface 112. In one embodiment, each instance of client devices 102,106, and 108 includes iterations of the same system software 110, anduser interface 112. System software 110 may exist in the form ofoperating system software, which may be Windows®, LINUX®, and otherapplication software such as internet applications and web browsers. Inone embodiment, user interface 112 allows for input into client devices102, 106, and 108. In another, embodiment, client devices 102 and 108include environment security program 200, security policy program 300,and security software 130. In exemplary embodiments, environmentsecurity program 200 determines a security level for an operatingenvironment. Environment security program 200 is discussed in greaterdetail with regard to FIG. 2. In exemplary embodiments, security policyprogram 300 determines a familiarity to and a historical security of anoperating environment. Security policy program 300 is discussed ingreater detail with regard to FIG. 3. Security software 130 can be anyprogram or set of programs that client device 102 and 108 can utilize todetermine an appropriate security policy for the client devices (i.e.what type of authentication challenge to present an individual utilizingthe client devices). In exemplary embodiments, security software 130receives input from security policy program 300. In another embodiment,client device 106 is representative of a client device not includingenvironment security program 200 and security policy program 300.

In exemplary embodiments, client devices 102, 106 and 108 includerespective instances of storage devices 114, 116 and 118 (client device102 includes storage device 114, client device 106 includes storagedevice 116, and client device 108 includes storage device 118). Storagedevices 114, 116 and 118 include information corresponding to thecorresponding client device 102, 106 or 108. Storage devices 114, 116and 118 can be implemented with any type of storage device that iscapable of storing data that may be accessed and utilized by clientdevices 102, 106 and 108 such as a database server, a hard disk drive,or flash memory. In other embodiments, storage devices 114, 116 and 118can represent multiple storage devices within client device 102, 106 or108. Data stored in storage devices 114, 116 and 118 can include, but isnot limited to: records of environments that client device 102, 106 or108 have operated in, records of devices operating in an environment,records of authentication failures (i.e. failed login attempts),activity the client device, and other information corresponding to theclient device. In exemplary embodiments, client devices 102, 106 and 108store information corresponding to the security of operatingenvironments in respective storage devices 114, 116 and 118.

In one embodiment, elements of data processing environment 100communicate through network 104 and wireless communications 120. Network104 can be, for example, a local area network (LAN), atelecommunications network, a wide area network (WAN) such as theInternet, or a combination of the three, and include wired, wireless, orfiber optic connections. In general, network 104 can be any combinationof connections and protocols that will support communications betweenclient devices 102, 106 and 108 in accordance with exemplary embodimentsof the present invention. In exemplary embodiments, wirelesscommunications 120 include protocols such as Bluetooth® and WiFi®communications between client devices 102, 106 and 108. In exemplaryembodiments, wireless communications 120 allows client devices 102, 106and 108 to broadcast and share information without having the clientdevices connected to network 104.

FIG. 2 is a flowchart depicting operational steps of environmentsecurity program 200 in accordance with an exemplary embodiment of thepresent invention. In one embodiment, environment security program 200initiates during boot up of client device 102 and 108. In anotherembodiment, environment security program 200 can initiate periodicallywhile client devices 102 or 108 are operating. FIG. 2 depicts anexemplary embodiment with regard to client device 102 booting up withindata processing environment 100.

In step 202, environment security program 200 identifies one or moreclient devices operating in a current environment. In one embodiment,during boot up phase of client device 102, environment security program200 utilizes wireless communications 120 (i.e. Bluetooth® and WiFi®protocols) to scan data processing environment 100 to identify devices(i.e. client devices 106 and 108) in the data processing environment. Inan exemplary embodiment, environment security program 200 utilizeswireless communications 120 to identify client devices 106 and 108 priorto client device 102 joining network 104. Client devices 102, 106 and108 periodically broadcast messages identifying the client devicesthrough wireless communications 120, allowing for a passive detectionand identification of the client devices operating in data processingenvironment 100. In exemplary embodiments, the passive detection andidentification of client devices 102, 106 and 108 allows environmentsecurity program 200 to identify the client devices in data processingenvironment without being connected to the client devices throughnetwork 104. Environment security program 200 utilizes wirelesscommunications 120 to detect and identify devices (i.e. client devices102, 106 and 108) close enough to communicate through wireless signals(i.e. Bluetooth® and WiFi® protocols).

In step 204, environment security program 200 determines a currentoperating environment corresponding to the one or more identified clientdevices. In an exemplary embodiment, environment security program 200determines the current operating environment of client device 102 to bethe one or more identified client devices (client devices 106 and 108from step 202). In an example, environment security program 200 onclient device 102 determines a current operating environment of clientdevices 106 and 108 for client device 102. In this example, environmentsecurity program 200 can compare the determined operational environmentwith previously determined operational environments stored in storagedevice 114. If environment security program 200 determines that storagedevice 114 already contains information corresponding to the determinedoperating environment, environment security program 200 updates theinformation in storage device 114 corresponding to the determinedoperating environment. If environment security program 200 determinedthat storage device 114 does not contain the determined operatingenvironment, environment security program 200 saves the determinedoperating environment in the storage device, allowing environmentsecurity program 200 to save information corresponding to the determinedoperating environment in the storage device.

In step 206, environment security program 200 determines informationcorresponding to the security of the current operating environment. Inan exemplary embodiment, environment security program 200 utilizeswireless communications 120 to determine information stored in storagedevices 114, 116, and 118 associated with client devices 102, 106, and108 that correspond to the security of the current operatingenvironment. The determined information can include, but is not limitedto: a device type, a manufacturer of the device, and other identifyingfactors corresponding to an identity of client devices 102, 106 and 108that storage devices 114, 116 and 118 can store. In exemplaryembodiments, devices utilizing WiFi® and Bluetooth® protocols canperiodically broadcast a hello message to an operating environment,wherein the hello messages include a device classification (devicetype), and a manufacturer of the device.

In decision step 208, environment security program 200 determineswhether an identified client device can provide additional information.In one embodiment, environment security program 200 determines whetheran identified device (i.e. client device 106 and 108) includesenvironment security program 200 and security policy program 300, whichallow for sharing of additional information through wirelesscommunications 120. When a determined current operating environmentincludes one or more client devices (i.e. client devices 106 and 108),environment security program 200 determines whether an identified clientdevice includes additional information for each identified client devicein the determined current operating environment. In an example withregard to client device 106, environment security program 200 determinesthat the client devices do not include environment security program 200and security policy program 300, and therefore the client device doesnot include (and cannot provide) additional information. In anotherexample with regard to client device 108, environment security program200 determines that the client device does include environment securityprogram 200 and security policy program 300, and therefore the clientdevice includes additional information. In exemplary embodiments,devices utilized by the same organization (i.e. client device 102 and108) contain environment security program 200 and security policyprogram 300, and allow for sharing of additional information betweendevices through wireless communications 120.

In step 210, environment security program 200 queries the identifiedclient device for additional information. In one embodiment, responsiveto determining that an identified client device (i.e. client device 108)can provide additional information, environment security program 200queries the identified client device for additional information. Theadditional information environment security program 200 queries caninclude, but are not limited to: a hash of a username associated with anindividual logged into client devices 102, 106 and 108, a count ofrecent authentication failures (i.e. failed log in attempts) on theclient devices of the operating environment, a hash of a usernameassociated with a recent authentication failure, or other informationcorresponding to the security of the current operating environment thatis stored in storage devices 114, 116 and 118. In exemplary embodiments,the additional information that client devices 106 and 108 share can bedefined through policies implemented on the client devices. In anexample, an individual or organization owning client devices 102, 106 or108 can define which information the client devices share. In thisexample, the organization owning client devices 108 defines that theadditional information that the client device shares is a hash of ausername associated with an individual logged into the client device,and a count of authentication failures occurring within the last hour.The additional information that client devices 106 and 108 share can bestored on storage devices 116 and 118.

In step 212, environment security program 200 receives additionalinformation from the identified client device. In an exemplaryembodiment, environment security program 200 receives information fromclient device 108 (stored in storage device 118) responsive to a querysent by the environment security program of client device 102. In anexample, client device 108 provides information indicating three recentauthentication failures associated with one username occurred on theclient device.

In step 214, environment security program 200 determines the currentsecurity of the current operating environment. In one embodiment,environment security program 200 utilizes information corresponding tothe security of the current operating environment (from step 206), andadditional information (from step 212). In exemplary embodiments,environment security program 200 utilizes information from clientdevices 106 and 108 to determine the current security of the determinedcurrent operating environment of client device 102. With regard toclient device 106, environment security program 200 can utilizeidentifying factors (i.e. device type, device manufacturer) that theclient device provides in step 206. With regard to client device 108,environment security program 200 can utilize identifying factors thatthe client device provides in step 206, and additional information thatthe client device provides in step 212. In an exemplary embodiment,environment security program 200 determines the current security of thecurrent operating environment to be a function of the count of recentauthentication failures within the determined current operatingenvironment (i.e. client device 108). In one embodiment, environmentsecurity program 200 stores the determined current security of thecurrent operating environment in storage device 114.

FIG. 3 is a flowchart depicting operational steps of security policyprogram 300 in accordance with an exemplary embodiment of the presentinvention. In one embodiment, security policy program 300 initiatesafter environment security program 200 determines the current securityof the current operating environment. Exemplary embodiments of FIG. 3are discussed with regard to client device 102 accessing storage device114 to determine information associated with the security of thedetermined current operating environment.

In step 302, security policy program 300 identifies historical datacorresponding to the current time period and the current operatingenvironment. In an exemplary embodiment with regard to client device102, security policy program 300 identifies historical data (i.e.records in storage device 114) stored in storage device 114corresponding to the current time period (i.e. indication of day of theweek, time zone, time of the day) of the client device in the currentoperating environment. The historical data security policy programidentifies can include records of environments that client device 102,106 or 108 have operated in, records of devices operating in anenvironment, and records of authentication failures (i.e. failed loginattempts). In a first example, security policy program 300 accessesstorage device 114 and identifies sixteen records corresponding to thecurrent time period. In this example, the identified records correspondto previous instances of client device 102 operating during the currenttime period (i.e. current time during the current weekday). In a secondexample, security policy program 300 accesses storage device 114 andidentifies twelve records corresponding to the current time period andthe current operating environment. In this example, the currentoperating environment is client devices 106 and 108 (determined in step204 of environment security program 200). The twelve records identifiedin the second example are a subset of the sixteen records identified inthe first example. In a third example, security policy program 300accesses storage device 114 and identifies three records correspondingto the current time period and the current operating environment andwhere a record indicates at least one authentication failure on clientdevice 102. In this example, the current operating environment is clientdevices 106 and 108 (determined in step 204 of environment securityprogram 200), and the authentication failures represent authenticationfailures on client device 102. The three records identified in the thirdexample are a subset of the twelve records identified in the secondexample.

In step 304, security policy program 300 determines a familiarity to thecurrent operating environment. In one embodiment, security policyprogram 300 utilizes data identified in step 302 to determine afamiliarity as a percentage representing how frequently client device102 is operating in the current operating environment at the currenttime period. In an example with regard to the previously discussed firstand second examples, security policy program 300 determines thefamiliarity to be the number of records corresponding to the currenttime period and the current operating environment (twelve from thesecond example) as a percentage of the number of records correspondingto the current time period (sixteen from the first example). In thisexample, security policy program 300 determines a familiarity of 75%. Afamiliarity of 75% indicates that 75% of the time that client device 102is operating during the current time period, the client device isoperating in the current operating environment.

In step 306, security policy program 300 determines a historicalsecurity of the current operating environment. In one embodiment,security policy program 300 utilizes data identified in step 302 todetermine a historical security level as a percentage representing howfrequently authentication failures occur in the current operatingenvironment at the current time period. In an example with regard to thepreviously discussed second and third examples, security policy program300 determines the historical security to be the number of recordscorresponding to the current time period and the current operatingenvironment, and where a record indicates at least one authenticationfailure (three from the third example) as a percentage of the number ofrecords corresponding to the current time period and the currentoperating environment (twelve from the second example). In this example,security policy program 300 determines a historical security of 25%. Ahistorical security of 25% indicates that 25% of the time that clientdevice 102 is operating in the current operating environment during thecurrent time period, the client device experiences an authenticationfailure.

In step 308, security policy program 300 sends the current security,familiarity, and historical security information to security software130 for determination of an appropriate security policy. In oneembodiment, security policy program 300 sends the current security (step214 of environment security program 200), the familiarity (step 304),and the historical security (step 306) information to security software130. In exemplary embodiments, security software 130 can utilize thecurrent security, familiarity, and historical security information toassist in determining a security policy for client device 102. Inanother embodiment, environment security program 200 and security policyprogram 300 can periodically operate and reevaluate the currentoperating environment while client device 102 is operating in thecurrent operating environment.
